+    /* Most existing libraries disagree with this test case, so a little
+       explanation of why PDCLib chose the implementation it did might be
+       necessary. All references are from ISO/IEC 9899:1999 "Programming
+       languages - C". Wording critical to the explanation is in UPPERCASE.
+       Input stream holds "-0xz".
+       6.4.4.1 Integer constants - states that '0' is a valid (hexa)decimal
+           constant, whereas '0x' IS NOT.
+       7.19.6.2 The fscanf function - states...
+           ...in paragraph 9 that "an INPUT ITEM is defined as the longest
+               sequence of input characters [...] which is, OR IS A PREFIX OF,
+               a matching input sequence".
+           ...in paragraph 10 that "if the INPUT ITEM is not a matching
+               sequence, the execution of THE DIRECTIVE FAILS; this condition
+               is a matching failure".
+           ...in footnote 242) that "fscanf pushes back AT MOST ONE input
+               character onto the input stream."
+           ...in paragraph 12 that either of the conversion specifiers d, i,
+              o, u, or x "matches an [...] integer whose format is the same as
+              expected for THE SUBJECT SEQUENCE of the [strtol|strtoul]
+              function".
+       7.20.1.4 The strtol, strtoll, strtoul, and strtoull functions - states
+           in paragraph 3 that "the EXPECTED FORM OF THE SUBJECT SEQUENCE is
+           that of an integer constant AS DESCRIBED IN 6.4.4.1".
+       These parts of the standard result in the following reasoning:
+       - The longest sequence of input characters which is a prefix of a
+         matching input sequence is "-0x" (negative sign, hexadecimal-prefix).
+         The 'z' is the first character remaining unread as "-0xz" is not a
+         (prefix of a) matching input sequence. This is according to 7.19.6.2
+         paragraph 9.
+       - "0x", without a valid hexadecimal digit following it, is not a valid
+         integer constant according to 6.4.4.1.
+       - "0x" is thus also not of the expected form for a strto[u]l subject
+         sequence according to 7.20.1.4 paragraph 3. (strto[u]l() would parse
+         it as zero, but leave the "x" in the final string, i.e. outside the
+         subject sequence.)
+       - "0x" is therefore also not a matching sequence to the i or x
+         conversion specifier according to 7.19.6.2 paragraph 12.
+       - The conversion should therefore result in a matching failure
+         according to 7.19.6.2 paragraph 10.
